Summary: A novel hollow HAp microflower with hierarchical mesoporous structure was designed through biomolecules induction and explored as macromolecular drug carrier. It showed higher drug loading capacity, sustained release behavior, and better biocompatibility. The excellent drug delivery property was attributed to the interaction among carrier, drug and medium environment, as well as to the pore structure and morphology of carrier. Overall, this work provides new insight into the optimization of macromolecular drug delivery performance.

Summary: In this study, a new hierarchical assembly strategy is proposed for the rational and precise construction of complex single-crystal superstructures. Unprecedented superclusters in Rubik's cube form are formed by aggregating oxohalide clusters as secondary building units. These Rubik's cubes then act as isolable tertiary building units to assemble diverse single-crystal superstructures. The captured intermediate assembly states provide a profound understanding of the assembly process at the atomic level.

Summary: This study presents a facile method for the preparation of hierarchical CoOOH, NiOOH, and MnOOH structures using a one-step coprecipitation route. The research reveals that K2S2O8 induces the oxidation state change of metal ion species, and the combination of NH3 diffusion and the presence of K2S2O8 enables the formation of hierarchical oxyhydroxide structures in aqueous solution at ambient temperature without heat energy or additional structure-directing agents. The hierarchical CoOOH structures exhibit excellent activity as electrocatalysts for the oxygen evolution reaction, outperforming many similar catalysts.

Summary: In this study, the structure-property relationships of ultra-small copper hydride (CuH) nanoclusters were investigated. The results showed that the CuH nanoclusters have a tetrahedral Cu4 core and a specific ligand structure, and their luminescence mainly originates from metal-to-ligand charge transfer and cluster-centered excited states. These findings provide new insights into understanding the structure-property relationship of CuH nanoclusters.

Summary: This paper aims to establish a scientific age segmentation criterion for elderly people based on thermal physiological demands. Field measurements and questionnaires are conducted to segment the age of elderly people based on thermophysiological functions in summer. The effects of basal metabolic rate, body fat percentage, and cardiac output on physiological indexes are analyzed, as well as the thermal sensation deviation degree and the environmental sensitivity of the elderly people at different ages. Results show that the age of elderly people is segmented into three groups, and comfort zones for air temperature, humidity, and air speed are identified for each age group. This study provides theoretical support for age segmentation criteria and differentiated environment design for elderly people in summer.

Summary: This study develops an intelligent proton-driven enhanced nanoconverter (PEN) that selectively accumulates in tumor regions and re-establishes the tumor microenvironment by depleting glucose, suppressing heat shock proteins, and promoting the activation of PANI. PEN can differentiate normal and cancerous tissues bidirectionally to minimize adverse effects, and achieves tumor elimination with high specificity through mild hyperthermia/immune response. PEN-induced adaptive antitumor immunity is effective for eliminating distant tumors and suppressing tumor metastasis and recurrence.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
